a. Environmental Risk Management
Environmental  management  is  a  mixture  of  science,  policy,  and  socio  economic applications. It focuses on the solution  of the practical problems that  humans  encounter  in
cohabitation with nature, exploitation of resources, and production of waste McGraw-Hill, P.831.
Investors and companies have become more and more conscious of the many ways that environmental  issues  affect  their  businesses,  presenting  not  only  challenges  but  also
opportunities.  Environmental  issues  generate  business  risks  that  have  to  be  carefully handled.  Regulations  related  to  businesses  and  the  environment  constantly  improve  and
almost  often  create  uncertainties  for  companies  bringing  significant  implications  for  their financial performance. Consumer‘s reactions and other environmentally motivated actions
create  serious  non-regulatory  r isks  that  may  reduce  a  company‘s  markets  or  affects  its
financial strengthFall, 2001. Case  1999  stated  that  many  business  leaders  realized  that  environment  factors  can
lead to economic growth around the world and agrees that environmental management can improve  the  bottom  line  performance  of  the  company.  Cost  savings  have  been  identified

  Reuse or recycle wastes   Reducing the amount of energy used, such as gas and electricity
  Cutting water consumptions   Lowering air emissions

b.    Difference Between Risk Management and Risk Assessment
According to the Environmental Protection Agency, a risk assessment is ―the evaluation of  scientific  information  on  the  hazardous  properties  of  environmental  agents,  the  dose-
response relationship, and the extent of human exposure to those agents‖ EPA Glossary of IRIS Terms.
Once  risk  has  been  assessed  and  characterized,  ―political,  social,  economic  and engineering  implications  together  with  risk-
related  information‖  are  gathered  ―in  order  to develop,  analyze  and  compare  management  options  and  select  the  appropriate  managerial
response to a potential chronic health hazard‖ EPA Glossary of IRIS Terms.  This process is  called  risk  management.  Together  these  steps  comprise  the  scientific  approach  to  risk
Stern, 2007. According  to  Pritchard  2012,  risk  assessment  is  defined  as  risk  estimation  and  risk
evaluation  or  can  be  said  as  risk  analysis,  while  risk  management  is  the  process  of implementing  decisions  on  managing  risks.  Risk  management  involves  identifying,
analyzing,  and  taking  steps  to  reduce  or  eliminate  the  loss  faced  by  an  organization  or individual.
